New tech holds the promise of changing your health — the problem is that sometimes it doesn’t work well

People love their gadgets. Fitness trackers are a great way to say I have a lot of disposable income and I care about my health. The problem is that a lot of the wearable tech out there doesn't necessarily do what it says it does.  I wrote about this for the CBC recently.

Epidemiology: Separating the Wheat from the Chaff

"There are only a handful of ways to do a study properly, but one thousand ways to do it wrong." We often talk on the podcast about the difference between good and bad studies, about studies that prove causation versus the ones that just show an association. The field of nutrition research is particularly problematic these days and even John Ioannidis is sounding the alarm. I recently wrote an article for Medscape about what readers…

041 – Cell Phones and Peanut Allergies

  Lost on the highway, the boys look for a cell phone signal and wonder about the potential dangers of their lifeline. Comedian Jacob Meza explores the possibilities of groin cancer while learning that some people may be scared of cell phones but are unwilling to give them up. Back in the studio, Chris and Jonathan discuss fava beans; the Larry King Show and brain cancer; subgroup analyses (which lie, they always lie); what male…

Did Marijuana Save Kevin Smith’s Life

  Kevin Smith is a great storyteller. So naturally, when he was on the Late Show With Stephen Colbert in May, he used up the entire segment to deliver what was essentially a 9-minute monologue without giving Colbert a chance to ask a single question. The segment was funny and poignant, and it provided a glimpse into a vulnerable, self-conscious man who views the scariest night of his life as the best thing to have ever happened…

Interview – Michael Marshall

  Jonathan and Chris interview Michael "Marsh" Marshall, project director of the Good Thinking Society and the vice-president of the Merseyside Skeptics Society in England. They discuss how Marsh and Simon Singh met; what a skeptical charity does; why Marsh interviews people with fringe beliefs; changing people's minds with nudges; the Good Thinking Society's campaign to stop the NHS from funding homeopathy in the UK; how PR releases get used by journalists to create "churnalism";…

Vitamin D and the Quest for the Perfect Tan

  You might look good with a tan, and of course there's vitamin D to think about, but the truth is that tanning is a very very bad idea. And the whole Vitamin D thing might not pan out in the long run. We banned tanning beds in Quebec for those under 18, but the risk of sun tanning hasn't really made it into the public consciousness. My latest for the Montreal Gazette: https://montrealgazette.com/opinion/opinion-deliberate-tanning-is-a-real...

040 – Omega-3s and the Mediterranean Diet

  Returning from a memorable fishing trip, the boys tackle the evidence behind omega-3s, a group of molecules known as "PUFAs!" (try not to laugh). They talk about the EPA; kinky and bent molecules; carnivorous chickens; cardiovascular disease and brain development. Also: how big trials can go wrong; and an interview with Dr. Emma Jones on palliative care, cultivating quality of life, collaborations in paediatric oncology, and myths about medicinal cannabis! Julia Belluz's article about…

The State of Skepticism

The recording was hosted by Grant Ritchey and Clay Jones of the Prism Podcast (and also of Science-Based Medicine), and featured Lydia Finch and Michael Marshall. You can find the episode by looking up the Prism Podcast on your favourite podcatcher or by clicking on this link. If you stay until the…
